HDPE ni iki?

HDPE igaragazwa n'ubucucike buri hejuru cyangwa bungana na 0.941 g/cm3. HDPE ifite urwego ruto rwo guterana kw'amashami bityo ikaba ikomeye hagati ya molekile n'imbaraga zo gukurura. HDPE ishobora gukorwa na chromium/silica catalysts, Ziegler-Natta catalysts cyangwa metallocene catalysts. Kubura kw'amashami byemezwa no guhitamo catalysts bikwiye (urugero: chromium catalysts cyangwa Ziegler-Natta catalysts) hamwe n'imiterere y'imikorere.

HDPE ikoreshwa mu bicuruzwa no mu bipfunyika nko mu macupa y'amata, amacupa y'isabune, mu tubati twa margarine, mu bikoresho by'imyanda n'imiyoboro y'amazi. HDPE ikoreshwa cyane mu gukora ibishashi by'umuriro. Mu miyoboro y'uburebure butandukanye (bitewe n'ingano y'ibikoresho), HDPE ikoreshwa nk'isimbura imiyoboro ya morti yatanzwe kubera impamvu ebyiri z'ingenzi. Iya mbere, ni nziza cyane kuruta imiyoboro ya morti yatanzwe kuko iyo igishishwa cyakoze nabi kigaturikira imbere mu muyoboro wa HDPE ("indabyo"), umuyoboro ntuzameneka. Impamvu ya kabiri ni uko bishobora kongera gukoreshwa bituma abashushanya bakora uduce twinshi twa morti. Abahanga mu by'imiti babuza ikoreshwa rya PVC mu miyoboro ya morti kuko ikunda kumenagurika, yohereza ibice bya pulasitiki ku bareba bashobora kuyibona, kandi ntizagaragara muri X-rays.
